'Original 'application iIe'dAAuguSt 8, 1921,'lS-eria1 'No' 490,604. "Divided land"I this application 'filed Toa'ZZ er1/lam t may concern.' l

Be it known that: 1 JAMES-Fi STRANA-inrit, a citizen :of the United States, residing'at Pittsburg, inthe county of :Contra Costa and State of California, have invented Aeertain new anduseful improvements in Resilient-Tire Rims; andl do` hereby declare the following to be a full, clear, andexact description of the inventioinlsuch as Will enable others skilled in the art to which it appertains to make and use the same.

The present invention is a divisional part ofthe invention for which, on'the Sth day of August, 1921, Serial No. 490,604, l filed an application for patent in the United States and relates to a sectional rim for a resilient tire and expanding and securing means both .for the rim and tire whereby the latter is supported and made secure.

Une object of the invention is the provision of means for securing together the sections of the rim and also forcing the beads of the tire against the flanges ofthe rim.

A further object'of this invention is the extending of the flanges of the rim so that a large proportion of the walls of the tire Will be supported and be. prevented from breaking when under excessive strain.

l/Vith these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of constructiomcombination and arrangement of parts` as will be hereinafter more fully described and claimed.

For a complete understanding of my involition reference is to be had to the folloiviiig description and accompanying drawings, in which:

Figure 1 is a transverse sectional view, illustrating a tire and its rim and constructed in accordance with my invention,

Figure 2 is a fragmentary plan vieu7 illustrating the means of connecting the sections of the rim,

Figure 3 is a fragmentary side elevation,

illustrating the securing of the rim with the tire thereon to the felly of a Wheel, and

Figure Llf isv a perspective View, illustrating the sectional rim fastener and tire eX- pander.

Referring in detail to the drawings the numeral 1 indicates the body of a tire which :serial in. 522,534.

isv constructedof rubber and mounted upon a metallic sectional frame 2' which is preferably constructed from a high grade of steel and includes side portions having abutting ,engagement at the crest of the tire and conthe purposes of the present invention maybe of any preferred construction.

A rim 12 is provided for the tire and consists of a. pair of sections 13 which have formed upon their outer edges tire engaging flanges 14 of considerable height for the purpose of engaging and'supporting a large .proportion of the side Walls of the tire, The sections 13 have pairs of diagonally arranged lugs 15 to be engaged by locking plates 16 which are provided with notches 17 to receive said lugs, consequently preventing separation ofthe sections of the rim 12. The locking plates 16 are :formed integrally With stems or Shanks 18 which are adapted to extend through openings in the rim l2 and which openings are formed by oppositely arranged recesses in the opposing or adjacent edges of the sections 13 of said rim. The sten/1s or Shanks 18 extend between the beads 7 of the tire and have formed thereon heads 19 provided with beveled or inclined faces Q0. W hen the plates 16 are in rini locking position, the heads-19 are so disposed as to force the beads 7 and the Wall of the tire 1 againstl the ianges 1d; of the rim 12 by the beveled faces- 20 engaging the beads 7. To remove the tire from the rim, the plates 1G are dis-- engaged from the lugs 15 which turns the heads 19 to extend parallel With the beads '7 whereby the sections of the rim may be separated and the beads of the tire removed from said rim and consequently the removal of the tire in entirety from the rim is thus obtained.

The rim 12 is mounted or positioned upon a felly 22 of a Wheel and is retained thereon by fastening means which include bolts 23 .extending through the felly and having V27. The cleatsV 26 engage the other tire flange 14 of the rim 12 and are of similar shape to the heads 24. Extensions 27 are formed on the cleats 26 and extend between the periphery of the felly and the rim. The

tire engaging flanges 14 are provided with 15 annular offsets 28 adapted to form seats for the ends of the heads 24 and the cleats 26 to engage.

While I have shown and described the preferred embodiment of my invention, it Will be understood that minor changes in construction, combination, and arrangement ofparts may be made Without departing from the spirit and scope'of the invention as claimed.

Having thus described myinvention what I claim is:

A device of theeharaeter set forth oomlprising a seetional rim, flanges formed on said rim, a tire mounted on said rim and engaged by said flanges and having` beads,

lugs formed 0n said sections of the rim,V

plates havingnotehes to receive said lugs,

Astems formed on said plates and extending through the rim and'between the beads o the tire, and heads formed on said stems and having beveled facesrto force the ,beads against the flanges When the: plates are moved into engagement with the lugs.

In testimony whereof I aiiX my signature in presence of two Witnesses. JAMES F. STRANAHAN. Witnesses:
